[Gmsh] Meshing in gmsh using iges from FreeCAD

Dear all

I am trying to use FreeCAD to make a 2d airfoil model and mesh it in gmsh.
I would like some help on this.

I have loaded the airfoil coordinates using this macro

https://github.com/FreeCAD/FreeCAD-macros/blob/master/ObjectCreation/Airfoil_Import_and_Scale.FCMacro

This creates a BSpline. Then I have added more curves to define my domain.
I want to specify the point distribution on these lines using "Transfinite
Line".

When I open the iges file in gmsh, I see that points are duplicated. End
point of one line has different number than first point of next line. How
to avoid this ?

Should I define the surfaces in FreeCAD itself or in Gmsh ? Are there any
examples available ?

Thanks
praveen
